GALVANIC BATTERY.

QFECEFICATION earning part of Letters Patent No. 344,523, dated June 29, 1886.

Application filed March 11, 1886.

T0 aZZ whom it may concern.-

Be it known that I, \VALDO L. GATES, of Saltersville, Bayonne City, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Galvanic Batteries, of which the following is a specification.

My improved battery is intended more es pecially for use with the automaticinstructor set forth in the patent to me, dated June 2, 1885, No. 319,224; but I believe it may be used with advantage in many other situations.

My invention will serve for a portable battery for use by physicians and surgeons in various exigencies where electricity is required. It will serve well in sending or receiving telegraphic or telephonic messages on railwaytrains in motion.' It is open,yet withoutdanger of slopping or overflowing. In what I esteem the preferable proportions, it may be inverted without spilling, because, although the aperture is open,the escape of fluid is prevented by the pressure of the air. The main body ofthe case or vesselin which my battery is mounted is a horizontal hollow cylinder with one flat end formed in one therewith. Another corresponding flat end is fitted to extend allttle way into the interior of the main part, and to form an absolutely tight-fitting plug therefor. The elements are bedded in pitch and held by screws, which are kept out of contact with the excitingfiuid by a covering of pitch. A screw holds one element against one end, and a corresponding screw holds the other element at the other end. The conductingwires are attached to the screws. Then the removable end or plug is in place, the only orifice connecting the interior ofthe casing with the outer atmosphere is about the mid-length, and connects with an open-ended funnel. The opposite side or lower side of the cylindrical case is provided with legs.

The entire construction may be rested on or sunk into a recess in the board or body ofmy instructor. It is firmly supported on legs formed in one with the cylindrical body.

The accompanying drawings form a part of this specification, and represent what I eon- Serial No. 194,768. (No model.)

sider the best means of carrying out the invention.

Figure 1is a side elevation. Fig. 2 is a central vertical longitudinal section. Fig. 3 is a vertical transverse section. Figs. 4 and 5 are elevations representing certain parts detached.

Similar letters ot' reierencc indicate corresponding parts in all the figures where they occur.

A is the body of the casing, made of hard rubber or other suitable strong non-conducting material, in the form of a hollow cylinder,

with one end closed and the other end open. A is a tunnel extending out at right angles to the axis of the cylinder A. The interior ofA connects with the external atmosphere through a small orifice, c, at the junction of A with A.

B is a plane end adapted to match tightly within the open end of A, and to form a practically-tight joint all around.

D is the carbon, and E the zinc. Each is made in the form represented, the part D being a hollow cylinder deeply notched, as shown, and the part E being a solid cylinder of smaller diameter fitting within D, but out of contact therewith. The carbon D is held in place by a thumb-screw, D, inserted through a hole in the closed end of the cylinder. The nut D aids in making a strong and reliable job. litch, m, is applied between the carbon D and the interior of the closed end of the cylinder. Pitch (correspondingly marked) is also applied around and over the nut. The zinc E is held by a thumb-screw, E, inserted through the removable end or plug B. Paraffine, a, is applied between the end of E and the adjacent surface of B.

G is the positive conducting-wire. It is connected by being wound around the screw D. G is the negative wire. It is connected by being wound around the screw E.

The pitch, m, and the parafiine, a, seal the joints around and prevent leakage around the screws D and E.

The legs A* are formed in one with the cy lindrical body A.

To charge my batteryIintroduce the chemicals in the form of a dry powder, using onethird (5*) bisulphate of mercury and twothirds (t) sal-ammoniac, simply pulverized and mixed. When required for'use, add sufficient water through the funnel A.

I attach importance to the fact that thebody A is cylindrical, andthat the plug Bis of corresponding form. This form makes it easy to make and maintain a tightjoint between A and B. o l v I attach importance to the legs, because they serve to reliably support the cylindrical battery in the required position.

I attach importance to the fact that the orifice a is on the top side and about the midlength. 7 The battery may be shaken without much disposition of the fluid contents to es; cape through this orifice I attach importance to the funnel A. It is a convenience in filling with water, andasafeguard against overflow.

I have in my experiments made the orifice a so small that the entire apparatus may be inverted without spilling, the fluid contents being retained by the pressure of the atmosphere.

Care should be taken in securing the carbon to have the deep notches lie in the position represented, one at the upper side immediately under the orifice a and the other at the lower side. I attach importance to these notches as allowing upward escape of hydrogen gas, and serving in a measure to reduce polarization. The notches also provide a clear space in line with the aperture a, through whichthe powder may descend to the bottom, instead of lodging on the carbon and obstructing 'the necessarily limited space which exists between the latter and the interior of the body A. These notches also, to a less degree, facilitate the emptying of the device: They should be so narrow as to subtract'but little an elementas such shall become necessary without damage to the body or cell A, or to any'other part of the apparatus.

I claim as my invention' 1. The battery described, having the body ,A,with its orifice a in the mid-length, in combination with the closing end or plug B, fitting tightly within it, and with provisions, as D 1 3., for attaching the connecting-wiresG G, as herein specified.

2. The carbon D, having two deep notches,

d d, arranged as shown relatively to the case A, having an aperture, a, and to the plug B,

zinc E, and. suitable connecting-wires, and means for attaching the same, as herein specified. i

3. The funnel A, .in combination with the casing A, having an aperture, a, at the point of junction with A, and with the tight-fitting end or plug B, and with provisions, as D E, for attaching the connecting-wires G G, as herein specified. I Y

4. The cylindrical body A, provided with a filling-orifice, a, in combination with legs A*, and with the removable end or plug B, and with provisions, as D E, for attaching the connecting-wires G G,ras herein specified.

In testimony whereofl have hereunto set my hand, at New York city, this 9th day of March, 1886, in the presence of two subscribing witnesses.
